Estimates of water-quality concentrations from two watersheds affected by the 2020 Cameron Peak Fire in Larimer County, Colorado

This data repository documents the input files, output files, and RStudio scripts used to quantify changes in water-quality concentrations after the 2020 Cameron Peak Fire in the North Fork Big Thompson River and Buckhorn Creek watersheds using the Weighted Regressions on Time, Discharge, and Season (WRTDS) method. A WRTDS model was developed using 12 years of pre-fire data (2008-August 13, 2020) and used to make predictions of what water-quality concentrations could have been on post-fire (August 13, 2020-2023) sample days had there not been a fire. This method may be a useful tool for post-fire water-quality assessments in the western United States.
